Updates on BLE-RC and RC transmitter firmwares
The BLE-RC project continues and is getting some updates again.

Miniaturization of my PCBs over 2024
Here is a small post about my progress in the area of PCB miniaturization over 2024.
JTAG breakout board
A breakout board for JTAG interface for ARM devices. You plug a JTAG probe at one end, and get pins to connect to your board. Available headers for probes a...
My first flex PCB
Last time I noticed that JLCPCB economy offer expands to flex PCBs, and, naturally, wanted to try one.
On JLCPCB panelization and economy offer
JLCPCB changes terms and conditions all the time, the situation described here applies to November 2024.
MK0 of BLE-RC transmitter
Continuing on BLE-RC transmitter.
RC transmitter using BLE [WIP]
An ESP32 RC remote with display that works over BLE
Moving on to RC transmitter
I’ve created a page for the development of the transmitter. Expect updates there. So far I’ve created a breadboard prototype that is able to c...
Finally RC kit project has a video!
I finally made a video about RC kit project:
Useful parts: TWS headphones
Another issue of "Useful parts", this time about TWS headphones.

Updates on RC truck and BLE-RC electronics
A latest video of state of the project (mid-august):
3D-printed RC kit for 1/87 vehicles
3D-printed RC conversion kit instead of usual metal parts
Updates on the projects
There were no updates for a long time due to my vacation, but finally here are some.
Arduino Nano Expansion Board
With options for motor, OLED display and Nunchuck
Useful parts: pogo pins
I’ve recently encountered spring-loaded pogo pins for PCB testing.
Crane updates
The crane mechanics is close to completion
Container crane, motorized [Idea]
Motorized container terminal crane in HO scale. This is currently only an idea.
Research on hardware selection
For the project, BLE hardware needs to be chosen. I’ve considered 2 options: using a ready-made BLE board and custom-made PCB.
BLE-based micro scale RC receiver
A 10x14mm PCB with nRF52 MCU
Motor board delivery updates
So, the JLCPCB and LCSC orders were made on April 28.
Motor control board
A small PCB to control motors in small-scale models. I’ve developed it as part of the portal crane.
Motor board for portal crane
For some time I’ve wanted to develop a PCB again. Last time I did that was around 2021, when I made LocoNet-equipped decoder and command station for...
Level-luffing crane, motorized and 3D printed [WIP]
3D printed and motorized model of a horse-head portal crane in HO scale
Introducing a 3D-printed DIY powered 2-axle chassis
A 3D-printed powered chassis for 2-axle locomotives.
